NEWS: document new hotplug enable/disable option on pci-root controller

A new 'target' subelement of the pci-root controller has been
introduced having a 'hotplug' property. This property can be used to
turn off or turn on the ability to hotplug/unplug devices to the slots
of the pci-root.

The new element can be used like this:

<controller type='pci' model='pci-root'>
   <target hotplug='off'/>
</controller>

This will turn off hotplug capability on the pci-root ports. To turn
the capability on, we set hotplug='on' above (which is also the
default).

+  * qemu: support disabling hotplug of devices on the pci-root controller
+
+    the <target hotplug='on|off'/> option is now supported for the
+    pci-root controller on i440fx-based (x86 "pc") machinetypes. This
+    can be used to disable hotplug/unplug of devices from this
+    controller. The default behavior is unchanged (hotplug is
+    allowed).
